(\partial)/(\partial x)(-4y^3sin(4x))

Solution

\frac{\partial}{\partial x} (- 4 y^{3} sin (4 x))

Solution

- 16 y^{3} cos (4 x)

Solution steps

\frac{\partial}{\partial x} (- 4 y^{3} sin (4 x))

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - 4 y^{3} \frac{\partial}{\partial x} (sin (4 x))

Apply the chain rule:

cos (4 x) \frac{\partial}{\partial x} (4 x)

= cos (4 x) \frac{\partial}{\partial x} (4 x)

\frac{\partial}{\partial x} (4 x) = 4

= - 4 y^{3} cos (4 x) \cdot 4

Simplify

= - 16 y^{3} cos (4 x)
